In the preceding three chapters, the influences of multiple factors such as high stress intervals (creep) duration, confining pressure, stress levels, etc., on the mechanical characteristics of rock salt creep–fatigue were systematically investigated. Based on experimental data and a combination of macroscopic and microscopic observations, an analysis was conducted to understand the diverse responses of internal rock salt structures to creep and fatigue, revealing the reasons behind the variations in creep and fatigue damage. The mutual interaction between creep and fatigue leads to a more intricate evolution of damage within the rock salt specimens, a feature also reflected in the results of acoustic emission monitoring.

摘要

In the preceding three chapters, the influences of multiple factors such as high stress intervals (creep) duration, confining pressure, stress levels, etc., on the mechanical characteristics of rock salt creep–fatigue were systematically investigated. Based on experimental data and a combination of macroscopic and microscopic observations, an analysis was conducted to understand the diverse responses of internal rock salt structures to creep and fatigue, revealing the reasons behind the variations in creep and fatigue damage. The mutual interaction between creep and fatigue leads to a more intricate evolution of damage within the rock salt specimens, a feature also reflected in the results of acoustic emission monitoring.
